Consider divided multilane highway in Congressional Avenue (fp = 0.98) that has six lanes (three lanes in each direction) and is on rolling terrain. The highway has 3.3m lanes with a 1.8m right-side shoulder and a 1.7m left-side shoulder. The posted speed limit is 85 kph. Formerly there were 1.2 access points per km, but recent development by Makati City Central Business District has increased the number of access points to 5.2 per km. Before development, the peak-hour factor was 0.95 and the directional hourly volume was 2500 vehicles with 9% large trucks and buses and 2% recreational vehicles. After development, the peak-hour directional flow is 3000 vehicles with the same vehicle percentages and peak-hour factor. What is the level of service before and after the development of Congressional Avenue? Round-off to the nearest value for the average passenger car speed in kph.

Given: 4-lane urban freeway; Interchange density 1.5/mile; Directional peak flow = 1950 veh/hr; 5% trucks; PHF = 0.90; 11 ft lanes; obstructions 4ft from right edge; Rolling terrain.Determine (a) LOS, and; (b) how much additional traffic could be accommodated before reaching capacity?
A four-lane urban freeway segment has a peak demand volume of 3,500 vehicles per hour for the two eastbound lanes. The PHF is 0.95 and there are no trucks, buses or RVs because the freeway is classified as a parkway and such vehicles are prohibited. The segment has 12 ft lanes, no lateral obstructions, 3 ramps within the influence area, and meanders through some beautiful rolling terrain. Assuming the road will be used by commuters and those familiar with the road, what is the flow rate (pcphpl)? Provide your answer to the nearest integer.
A divided multilane highway is being designed on rolling terrain. The LOS is desired to be no worse than LOS C. The highway will have five access points per mile, 11-ft lanes, a 4-ft shoulder on the right side, and 2-ft shoulder on the left. The peak-hour factor is 0.84 with 13% heavy vehicles. How many lanes should be constructed if the expected DDHV is 4000 vehicles/hr
QUESTION 1 A four-lane urban freeway segment has a peak demand volume of 3,500 vehicles per hour for the two eastbound lanes. The PHF is 0.95 and there are no trucks, buses or RVs because the freeway is classified as a parkway and such vehicles are prohibited. The segment has 12 ft lanes, no lateral obstructions, 3 ramps within the influence area, and meanders through some beautiful rolling terrain. Assuming the road will be used by commuters and those familiar with the road, what is the flow rate (pcphpl)? Provide your answer to the nearest integer.
6.14 A freeway segment currently has four 11-ft wide lanes and a 3-ft right shoulder in the southbound direction. It is operating in LOS B with a traffic density of 15.6 pc/mi/ln and a peak-hour factor of 0.85. The freeway is on level terrain with 15% heavy vehicles, and currently has no on- or off- ramps within a distance of three miles upstream and downstream of the mid-point of the analysis section. New interchanges are to be constructed that would result in 6 on- and off-ramps within the distance of three miles upstream and downstream of the mid- point of the analysis section and total traffic volume is projected to double, with the same percentage of heavy vehicles, and the peak-hour factor going to 0.95. What would the new LOS and density be after the interchange construction and new traffic conditions?
A freeway is to be designed for the following conditions:Heavy vehicle adjustment factor = 0.80Total ramp density =0.75 ramps/miTwo lanes each way with average lane width = 12 ftRight side lateral clearance = 4 ftNo. of lanes in one-way = 2 What is the free flow speed (FFS) in mph of the basic freeway segmen?
A four-lane rural freeway segment has a 510 m grade length of 2% upgrade followed by a 630 m grade length of 3%. The freeway has 3.4-m lane, 1.5m left-shoulder lateral clearances and interchanges spaced at every 25 km. During the peak hour, there are 6% trucks, 2% buses, 2% recreational vehicles and the rest are passenger cars. Driver population adjustment is determined to be 0.90, peak hour factor is 0.90 and the BFFS is 110 km/h. At present, the freeway operates at capacity during the peak hour in the direction in question. If an additional 3.4 m lane is introduced, and all other factors stay the same, what will be the new level of service?
6.9 An eight-lane freeway (four lanes in each direction) is on rolling terrain and has 11-ft lanes with a 4-ft right-side shoulder. The total ramp density is 1.5 ramps per mile. The directional peak- hour traffic volume is 5400 vehicles with 11% heavy vehicles. The peak-hour factor is 0.95. It has been decided that heavy vehicles will be banned from the freeway during the peak hour. What will the freeway's density and LOS be before and after the ban? (Assume that the heavy vehicles are removed and all other traffic attributes are unchanged.)
A 4-lane rural basic freeway segment is with hourly flow rate = 1528 pcphpl. The interchange density is 0.8/km, average lane width is 3.7m, sufficient lateral clearance. Using the HCM 2000 procedure, the estimated FFS speed (kph) and the current segment LOS are and respectively. ............. а. 104 & LOS B b. 107 & LOS E С. 108 & LOS D d. 114 & LOS C е. none
A new basic freeway segment will have 3 lanes in each direction. The left and center lane each has a width of 12 ft while the width of the right lane is 13 ft. The left shoulder is 4 ft while the right shoulder is also 4 ft. There are 2 interchanges within 6 miles (3 miles upstream and 3 miles down stream).The site has level terrain, the design speed is 80 mph the hourly design volume is 5250 veh/h, which includes 9.0% trucks and buses. The peak hour factor is 0.870. Calculate FHV, VP, FFS, LOS Show all work
A divided hwy is to be built in a suburban level terrain, forecasted AADT = 12,000 vehicle/day, with 5% trucks, the fraction of traffic in the peak direction of flow is 0.7, PHF = 0.85, desired LOS is "C", assume K factor = 0.12, the number of lanes that will be needed in each direction is:
A new four-lane divided multilane highway (two lanes in each direction) is being planned with 12-ft lanes, 6-ft shoulders on both sides, and a 50-mi/h speed limit. One 3% downgrade is 4.5 mi long, and there will be 4 access points per mile. The peak-hour directional volume along this grade is estimated to consist of 1800 passenger cars, 140 SUTs, and 60 TTs. If the peak-hour factor is estimated to be 0.85, what level of service will this segment of highway operate under? What is the percent trucks - PT? What is the value of the passenger car equivalence factor - ET? What is the heavy vehicle factor - fHV? What is the median adjustment factor - fM?
